Good To Know

Q: How many gaskets come with this item? A: This listing covers a single muffler gasket unless the title states otherwise. Check your exhaust layout to confirm how many you need.

Q: Should the gasket be replaced every time the muffler is removed? A: Gaskets compress and set with heat, so replacing them during reassembly helps maintain a proper seal. Reusing an old gasket can lead to leaks.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
